But then again, a very reliable EE type who has designed several communications controllers said that most that he's seen only protect for accidental installation to a 48V phone circuit. I would check out the specific vendors directly and see if they might have some solutions. Another interesting problem I've heard of as a bigger problem is making sure that your wiring closet protects your data circuits from Mr. Telco Repairman. I've heard of more than one case where phone circuits were connected to a data line, or a data line was disonnected when moving phone extensions etc... I guess that some guys think that all punch-down blocks are phone lines.
